Gates" in ancient times had a significance that does not hold in the modern world. Cities then were enclosed by walls for protection; gates in the walls let people in and out to do their business, but were also the weak points in the cities' defenses. In the Bible, cities on one level represent the minds of individual people. On a broader level, they represent beliefs shared by a community. The gates, then, represent openings where the Lord can feed us an understanding of truth and a desire for good. They also represent points where the hells can invade and sway us with false ideas and evil desires. We are kept in balance during our lifetimes, with influences from both the Lord and from hell. Ideally, we will over our lifetimes continue to invite the Lord farther and farther in and drive the hells back until ultimately the Lord can occupy our minds completely. And that point our belief in Him and His power and love will hold the gates and deny evil any entrance. As individuals, we at that point become angels. As communities, we at that point become part of the Lord's church. And at that point the gates become an entry point, introductory truths that allow people to enter churches and start bringing the Lord into their lives.

2850. 'And like the sand which is on the seashore' means a whole multitude of correspondent facts. This is clear from the meaning of 'the sea' as facts in general or a gathering together of them, dealt with in 28, 2120, and from the meaning of 'the sand' as facts individually and separately. Facts are compared to 'the sand' because in the internal sense the particles of stone from which the sand is formed mean facts, 643, 1298. Both comparisons are made here - that they will be multiplied 'as the stars of the heavens' and 'as the sand on the seashore 'because 'stars', or cognitions, are related to the rational, whereas 'the sand of the seashore', or facts, are related to the natural. When the things that belong to the rational man, namely the goods and truths present in cognitions, so exist in accordance with the things that belong to the natural man, that is to say, with facts, that they make one or mutually support each other, they in that case correspond. The Lord brings man's rational concepts and his natural images into this state of correspondence when He regenerates him, that is, makes him spiritual. It is for this reason that both the stars of the heavens and the sand on the seashore are mentioned here. Otherwise one phrase would have been sufficient.
